Best Drone Flight Controller

drone controller

Building your own drone is a fun and exciting experience. With the number of options out there, it’s easy to get a complete kit with everything you need to build a high-quality device. However, if you’re experienced with building these flying machines, you might have specific needs that extend beyond what a kit provides you with.

A flight controller is a critical drone element. Without one, you’ll have a device that will look cool but won’t be able to fly. The controllers may not look like much, but the small circuit boards enable you to take flight and stay in control while doing so. Below, you will find some of the best drone flight controllers on the market to help with your current or upcoming build.

Quick Summary

  • The Pixhawk PX4 Flight Controller by Readytosky is an option for anyone building a drone. This style has been around a while, so it’s tried and tested to be both effective and reliable.
  • Another good option is the DJI Naza-M Multi-Rotor Flight Controller System. This is an easy-to-use controller that includes GPS among other functional features.
  • The F7 AIO Flight Controller is an affordable model that also comes with fully functional Bluetooth capabilities. There are a lot of controllers with similar features, but this one stands out thanks to its unique aspects and low price point.

Who Should Get This?

If you’re building a drone, you need a flight controller. There’s no way around it. You can have all of the other pieces assembled, but without this piece of the puzzle, you’ll remain grounded. Think of the flight controller as your drone’s brain. It might be a small part of the overall construction, but its role is absolutely critical. No matter what type of drone you’re building, you need a quality flight controller.

If you’re building your drone from a kit, it might already come with a flight controller. If that’s the case, you don’t need to get one specifically for your build. However, you might want to consider upgrading to one of the options listed here. Chances are, the kit you purchased will function well with the included flight controller. Just make sure it comes with one when you send in your order.

Best Drone Flight Controller: What to Consider

Processor Speed

A flight controller’s processor speed is an important thing to consider. General speed has increased dramatically over the last few years. 32-bit processing is the norm these days and faster processors are all built using this sort of design.

An F4 or F7 processor is recommended for a modern flight controller. The ones here give you enough speed to power your drone effectively and reliably. F4 processors can run at an operating frequency of 168 Mhz, while an F7 processor can run at 216 MHz. F4’s will be more affordable and common, but if you want the fastest speed possible, look for an F7.

Sensors

Sensors are another important consideration. Their quality determines how well your drone operates as well as how easily you can control it. Important aspects of flight are affected by sensors, including the barometer, gyroscope, and accelerometer. All of the options you’ll find here come with quality sensors that you can expect to perform well.

Compatibility

You want to make sure that your flight controller is compatible with the receiver you use to physically control the drone. Most modern flight controllers, and all of the options you’ll find here, are compatible with a wide range of receivers. As such, you won’t need to worry about their ability to interact with one another. Even so, always be sure to check that the flight controller you’re looking at will work with your receiver.
